How does the electric ball valve control the opening of the valve

How does the electric ball valve control the opening of the valve? You will understand after reading it.

The flow characteristics can be linearized and can replace the old control valve;
Small volume and light weight;
Imported key parts and components, high reliability
Genuine materials and long service life;
The valve is made of stainless steel, high-grade and beautiful;
4-20mA intelligent regulation can be selected;
There are normal temperature type, medium temperature type and 1.6-4.ompa.
Nominal diameter: dn8-400
Nominal pressure: pn1.6,6.4mpa
Valve body material: cast steel, stainless steel
Sealing material: polytetrafluoroethylene, stainless steel
Applicable temperature: normal temperature type – 40 ~ 180 ` C; High temperature type – 40 ~ 450 ` C
It is not only suitable for controlling general fluid medium, but also especially suitable for controlling pulp, sewage, medium containing fiber and micro solid particles. It is widely used in electric power, petroleum, chemical, metallurgy, papermaking and other industries.

Switch type means that the electric actuator can only control on and off; The regulating type means that the electric actuator can control the opening of the valve by inputting or outputting a control signal of 4-20mA or 0-10V to regulate the flow of the medium;

The switch type electric actuator mainly needs quick and sensitive switch response, quick switch, generally between 8-15 seconds, and long service life;
The main performance of the regulating electric actuator is reflected in the control accuracy, which is generally within 1% of the error, and can accurately adjust the opening and flow.

The electric switch ball valve is generally used for two-position switch off. It has two positions of full open and full close. It is used to open or close to conduct and cut off the working medium inside. It has no special requirements for the flow characteristics, but the requirements for the switching speed and leakage are higher than those for the control valve.

The electric regulating ball valve is mainly used to regulate the flow, pressure, liquid level and other parameters of the medium. There are high requirements for the flow characteristics during the whole process from opening to closing; The requirement for stability of opening degree between on and off is higher than that of on-off valve..

Please specify when ordering electric ball valve

1. Power supply voltage: AC220V, AC380V, DC24V;
2. Medium type, temperature and pressure of ball valve;
3. Electric ball valve switch control or regulation control;
4. What control signal and what feedback signal are required;
5. The shape or flow characteristics of the ball through hole you need.
